The gear assembly comprises a helical gear with a bidirectional bearing, a clutch shell with a unidirectional bearing meshing with the helical gear, a spring positioned between the helical gear and the clutch shell, two pinions respectively positioned beside the clutch shell and the helical gear, and a shifting shaft mounted transversely through each of the two pinions, the helical gear, the bidirectional bearing, the spring, the unidirectional bearing, and the clutch shell. The upper lid comprises a fastener and a switch cover co-acted with the fastener and detachably contacting the helical gear and the clutch shell.

A mixing hub for use in semiconductor processing tools is provided. The hub may include a plurality of ports arranged about an axis, a mixing chamber, and a plurality of flow paths. Each of the flow paths may fluidically connect a corresponding one of the ports to the mixing chamber and each flow path may include a first passage, a second passage, and a valve interface. Each valve interface may be configured to interface with a valve such that the valve, when installed in the valve interface, is able to regulate fluid flow between the first passage and the second passage. Each valve interface may be located between a first reference plane that is perpendicular to the axis and passes through the corresponding port and a second reference plane that is perpendicular to the axis and passes through the mixing chamber.

In some aspects, the present disclosure pertains to systems for forming hydrogel compositions, the systems comprising a first reservoir containing an iodinated polymer composition that comprise an iodinated polymer having multiple cyclic imide ester groups, a second reservoir containing a buffered diluent solution having a first pH that comprises water, a first buffering agent and a polyamine compound, and a third reservoir containing a buffered accelerant solution having a second pH that is higher than the first pH and comprises water and a second buffering agent.

A device for storing and mixing bone cement components. The device includes a housing, a safety device, and a vacuum indicator. The housing defines a mixing chamber configured to store a first bone cement component therein. In a first safety position, the safety device prevents contact between the first bone cement component and a second bone cement component in the mixing chamber. In a second safety position, the safety device permits contact between the first and second bone cement components in the mixing chamber. The vacuum indicator restricts movement of the safety device from the first safety position to the second safety position when in a first vacuum indicator position. The vacuum indicator permits movement of the safety device from the first safety position to the second safety position when in a second vacuum indicator position.
